Set a passive income or net-worth goal. The planner runs a year-by-year simulation showing when you'll hit it — based on your starting position, savings rate, and assumptions about growth and yield. Pull the sliders to stress-test what changes the answer.

The simulation: Every year, existing properties grow by the capital growth rate. Rent grows separately. Interest, holding costs, and tax effects flow into cashflow. Cashflow + your savings accumulate. If auto mode is on, the simulator buys a new property whenever you have enough cash + accessible equity AND a basic serviceability check passes.
Accessible equity: Banks generally let you borrow against 80% LVR on existing properties. Accessible equity = (total portfolio value × 0.80) − total debt. New property deposits can come from this equity (cash-out refinance) plus your cash savings.
Serviceability check (simplified): The simulator only allows a new purchase if your total debt service ratio (interest + holding costs) stays under 40% of your gross household income (wage + rent). Real bank serviceability is much stricter — uses HEM, assessment rates 2-3% above actual, stress tests. Use a broker for actual borrowing capacity.
Tax modelling (simplified): Negative cashflow gets offset against wage income at your marginal rate (assuming current rules continue). Budget 2026 changes — which would quarantine losses on established properties — are NOT modelled here. Use the CGT & Structure calc for full Budget 2026 impact.
